Quinn's Diana Agron's looking pretty BAMF-y on the motorcycle. And I'm always down for some pretty aliens. (For any Hunger Games fans out there: There's a large movement to get Alex Pettyfer (the guy in the clip) cast as Peeta in the film adaptation.)

We won't reach Alpha Centauri until the 24th century...unless we have an energy breakthrough

If you take humanity's current energy and technological capacity and project a steady increase into the future, the chances of us reaching the stars any time soon look bleak. Even our nearest stellar neighbor is at least 300 years away.

Of course, humans could technically reach Alpha Centauri long before the 2300s. The Voyager probes, for instance, are headed into interstellar space, and it wouldn't be that difficult to take another probe and aim it in the rough direction of Alpha Centauri. But that probe would still take a long time to get there, its instruments would probably give out long before it arrived at the star, and what data it could provide would be hugely limited. (via)
